9. Explain clearly how the use of enzymes can enhance the power of electro-
chemical immunosensors.
10. Explain clearly why and how the response of glucose oxidase-based enzyme
electrodes is in¯uenced by ¯uctuations in the oxygen tension.
11. Use equations to explain why and how an increase in the sensitivity of an
enzyme electrode is often coupled to a narrower linear range.
12. Explain clearly why highly selective individual electrodes are not desired for the
operation of sensor arrays.

13. Discuss the major sources of errors in amperometric monitoring of blood
glucose.
